' To all whom it ma concern:

. to P willbe operable'from the driver by means of which the en ine may be turned Be it known t at I, HENRY MALLARD, a

' citizen of the United States residing at Stockton, in the county of San Joaquin, State of California, have invented certain new and-useful Improvements in Starting Devices for Vehicle-Motors; and I do declare the following to be a full, clear, and exact description ofthe same, reference being had to the accompanying drawings and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in devices for starting the engine of motor vehicles, .and is rticularly adapted to be used on those 0 the Ford type.

-The rincip'al object of the inventionis uce a device for the purpose which over two complete revo utions with every singlefu movement of the operating means.

rther object is to produce a device which will be concealed under the hood of the engine and which may be installed on the en e without'neces'sltating any structural c anges therein.

' A further-object of the invention. is to produce a simple and inexpensive device and yet one which will be exceedin ly efi'ective I designed.

These ob ectsI accomplish by means of such structure andrelative arrangement of, parts as will fully appear by a 'rusal of the'following specification and c aims.-

5 In the drawings similar characters of ref erence indicate. corresponding parts in the several views,

Figure 1 is an outlined side elevation of a Ford engine, showing my improved starter installed in connection therewith.

F1g.. 2 is a front elevation of a gear an ratchet drum.

Fig. 3 is a sectional view of the same.

Fig. 4 is a detached view of a clutch mechanism for throwing the actuating mechanism into connection with the engine shaft.

Referring now, more particularly to the characters of reference on the drawings, the numeral '1 denotes the engine. and 2 the crank handle having the usual ratchet clutch 3 on the inner end thereof, the handle being Specification of Letters Patent.

s seat, and

' turn meshes wit Patented Mar. 30, 1920.

the clutch 3 will on age a pin on the forward end of the crank 5121f?- This latter feature is not shown, as it is the usual construction on engines of the type mentioned.

A bracket 4' is mounted on the engine at a suitable point adjacent its forward end, and to this bracket is bolted a vertical drum or casing 5, centrally in which is mounted a shaft 6. On this shaft,'out side the casing arid to the rear thereof, 1s turnably mounted a sprocket wheel 7, having sprin do s 8 thereon adapted to engage a ratc at w eel 9 secured-to the shaft 6.- A coiled spring 9 is secured to the casing and to the s rocket wheel 9 in such a manner that sai wheel will always return to its normal position.

A gear 10 is keyed to the shaft 6 inside the with a pinion 11 which in an internal-gear 12 turnably mounted. on the shaft.

casing 5, meshing A small pinion 13 meshes with the gear 12 only, the shaft 14 of which pinion being mounted in the casing 5 an projecting through the forward'end thereof, aving'on such projecting portion'a chain sprocket 15- from which a chain 16 leadsto a s rocket 17 loosely mounted on'the shaft 2' o the crank handle member 2 forward of the clutch 3.

On the forward face of the'sprocket wheel 17 are ratchets18 adapted to en ge with a .ratchet member 19 secured to t e shaft 2 when the same is moved to en ge the clutch 3 thereof with the engine sha The above described mechanism is actuated by the driver of the vehicle in the following manner:

A chain 20 is normally wound on the adapted to move toward the engine so that sprocket wheel 7 and secured thereto at one end so as to permit of the rotation of said wheel for a proximately one revolution. The outer en of this chain is secured to a cable 21 which passes around a pulley 22 secured to the engine frame and thence to the lower end of a dal lever 23 pivoted to the floor of the ve icle adjacent the dashboard and in a suitable location.

Thus by ushing the pedalv forward with the foot, e chain 20 unwinds from the sprocket wheel 7, causing the same to retate, and so ultimately imparting motion to the sprocket wheel 15, the ratio of the various gears being such that the speed of the sprocket wheel 15'will be double that of the initial wheel 7.

' pedal 23 to return to its normal position.

In order to throw the clutch ratchets 18.

and 19 into engagement and move the crank handle shaft 2 to engage the engine shaft, I provide a push rod 24 attached at one end to the pedal 23 above the pivotal point thereof. The other end of the rod has a pair of spaced eyes 25 through which projects a rod 26 connected at its other end to one end of a bell crank 27 pivoted to the engine base, which in turn is o erativel connected to the sleeve of the ratchet mem er 19.

A. spring 28 is interposed on the rod 26 between one of the eyes Y25 and a collar 29 on the rod so that when the rod 24 moves forward with the movement of the pedal 23, the first result is the compression of the spring 28 until the strength thereof is sufficient to cause the bell crank 27 to move the shaft 2 to engage the clutch 3 thereof with theengine shaft and also the ratchets 18 and 19, which latter action of course places the sprocket wheel 17 .in operative connection with the engine shaft. I

' After said ratchets and clutch are once in engagement any further forward movement of the rod 24 merely causes the spring 28 to 'be further compressed, thuspreventing bending or breaking the rod 26 or any of the parts connected thereto.

When the pressure on the pedal is released, the ratchets 18 and 19 are of course disengaged, both by the action of the spring 28 and by that of the sprin normally provided on the crank hand e shaft which tends to normally hold the same out of engagement with the engine shaft.

From the foregoing description it will be readily'seen that'I have produced such a device as substantially fulfils the object of,

the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by ,the appended claims,

Having thus described myinvention what I claim as new and useful and desire to secure by Letters Patent is: 1. A starter for vehicle motors com ris ing a sprocket wheel loosely mounte on as en the crank handle shaft of the motor, a cas ing secured tothemotor, a sprocket wheel mounted in the casing and operatively connected to the first named sprocket wheel, a ratchet wheel mounted on the casing and connected with the sprocket wheel therein with a predetermined ratio of rotation, and a common means operable by the 'driver of the vehicle for actuating the ratchet wheel to turn the sprocket wheels and at the same time moving the crankhandle shaft into ov 'rative connection. with the sprocket w}; eel thereon and with the motor crank s aft.

' 2: A starter for vehicle motors comprising a sprocket wheel loosely mounted on the crank handle shaft of the motor, a casing secured to the motor, a sprocket wheel.

mounted in the casing and operatively connected to the first named sprocket wheel, a ratchet wheel mounted -on the casing and connected with the sprocket wheel therein with a predeterminediratio of rotation, a

pedal lever mounted on the floor of the vehicle within reach of the feet of the driver, I

means connected to the edal' and to the ratchet wheel whereby t e same may be the'said shaft may be moved vinto'connection with the motor crank shaft and with the sprocket wheel on the crank handle shaft simultaneously.

3. A starter for. vehicle motors comprising a sprocket wheel loosely mounted on the crank handle shaft of the motor and adapted to be laced in turning connection with such sha t when the latter is moved into connection with the motor crank shaft, a casing secured to the motor, a sprocket wheel mounted in the casing and o erativel connected to the first named sproc et whee a ratchet wheel mounted on the casing, gearing in the casing between the ratchet wheel and'the sprocket wheel to give the latter a predetermined ratio of turning relative to the former, and means 0 erable by the driver of the car whereby t e ratchet 'wheel may be turned through one revolu-,

tionwith each movement of such operating means.

In testimony whereof I afiix my signature-
